New Defender Rage/Hate Thread

So if I’m reading LR’s info correctly that’s 330lbs before you have to start subtracting from your payload. So if you want to have a 770lb tongue weight you have to subtract 440lbs from your payload.

^ Correct.


You didn't read the spec. Can you please read the spec? Your common sense is failing miserably here, and you've again incorrectly quoted the LR tongue weight as 330lb, which it's not.

You don't have to 'work your way back and forth through the math. There is no math. You simply follow the stated max tongue weight, max axle weight, max gross and combined weight. The math was done for you. Read the spec. There's a LOT of work that's put into this, a lot more than your common sense will provide.

Generally agree except the math point is constrained by the spec:

  • For light-duty full-size pickups (GVWR < 8,500 lbs.), SAE J2807 assumes that the tow vehicle includes any options with higher than 33 percent penetration;
  • It assumes there is both a driver and passenger in the vehicle, each weighing 150 pounds;
  • It assumes that tow vehicles also include up to 70 pounds of aftermarket hitch equipment (where applicable); and
  • For conventional trailer towing, SAE J2807 assumes that 10 percent of the trailer weight is on the tongue.
I'm also assuming that every manufacturer is now compliant to J2807 such that their specs are consistent.

Not a subscriber to SAE, not going to pay $80 and the 330 lb rating is from LRs own web site for both the new Defender and Range Rover.

If I get a new Defender I’d just stay under 770lbs. LR’s own documentation says that’s 330Lbs with full payload capacity and 770 with 440lbs less payload capacity. On LR3/4 tongue weight ratings had to do with hitch designs the higher rated one was shorter. Also in Europe they run with significantly less tongue weight than we do here IIRC just over 5% tongue weight isn’t uncommon.

Plenty of great information to read if you're interested. Layman explanation is that in EU since trailering speeds are far lower and thus the stability issues are also a less of a concern. Physics of course are the same on both continents.

So you're going to ignore the test method, ignore the footnote next to the stated tongue weight, and go back to claiming 'common sense.'

Hey guys, the earth is flat. I know that bc I have common sense. Get outta here with your science and crap.

Yeah they usually don’t tow faster 50mph.

Not ignoring anything. The advertised tongue weight has dropped to 330 lbs as the SAE spec came into play. LR is less than a 1/2 ton pickup when compared to Ford. Good to know.

Not ignoring anything, just pretending to play engineer while you ignore the published specifications, test method, and measurement criteria.

You also ignored the part where the rover isn't a pickup truck at all... soo..... yeah. Can't help ya there. Or in general I guess. :ROFLMAO: :ROFLMAO: :ROFLMAO:

Been down this path before on towing with others. It is why some in that conversation moved to LC200's and F250's. Bottom line is that per the spec LR D7 architecture is less than a 1/2 ton pickup. I'm fine with that. Everything is a compromise at some point. Example - air suspension prevents use of Weight Distribution Hitches. I'm OK with that. I do think potential LR customers will see the 330lb rating and go - ******! and walk away without a further investigation. I would not have marketed a vehicles tow rating assuming full payload. Take a survey of travel trailer tongue weights and you're going to find nearly EVERY ONE of them has a tongue weight greater than 330 lbs. At a cursory level that eliminates Land Rover completely as a candidate for a Tow Vehicle.


Will be interesting to see the Ineos Grenadier spec.

Have a nice day. Go fight with someone else.

From a legal standpoint it might not be a bad idea to advertise the full payload rating.

You guys may want to watch this documentary. I am only 40 minutes into it but the guy is about to have a nervous breakdown because he has to fix his Defender every day.
My bet is that they would be happy to have a new one.

The travel trailer vendors spec dry tongue weight from which options add to it from there, either increasing or decreasing tongue weight. It would be prudent for tow vehicle candidates to spec without full payload and let the consumer close the gap between TV and trailer depending on personal needs. Blowing yourself out of the water from the get-go is pure insanity.

Yeah they usually don’t tow faster 50mph.

Actually, UK is 60mph on the motorway and dual carriageways where the National Speed limit applies; on single carriageway roads it's 50mph. Unless it's a commercial vehicle (so some dual cab piuckups and all single cab pickups) in which case, it's lower:

France is 100km/h (62mph) on the Autoroute, can't remember on the RNs etc, but given I was generally towing a trailer using a RHD XLWB Transit minibus I wasn't going to be going that quick anyway.

But yes, a European trailer (of nearly any type) is very different geometry to an American or Australian trailer, withe the axles much closer to the midpoint, lower weight generally (never over 3500kg, because if it was over that then you're into a using a truck (over 3500kg GVM), and infrequently over 2500kg unless a commercial stock trailer or car/plant trailer). And as others have said, a 5-7% noseweight is much more common... which means that there is still some weight on the wheels that do the steering....
